I'm new to this, so please be patient.
This is my first computer upgrade. I went to my local computer parts store and said I wanted to start building computers. The owner very kindly gave me a free Dell Dimension 3000 without a hard drive, and gave me a WD cavalier 80 GB Hard drive to replace it. I tried putting it in when I got home and it turns out none of the connectors fit from the motherboard into the new Hard drive. Am I doing something wrong? Are there adapters I can buy?
You probably wasting your time since the dim 3000 is obsolete now but you should be able to install a hard drive. Check the manual here. You need to buy sata cables to connect to MB and have available power supply cables from the power supply. The hard drive needs an operating system but it is not worth spending any money on windows. XP is the unsupported insecure operating system that runs on that model. If you have XP install disk you can use that but do not connect to the Internet. It is unsafe. There are no updates for XP available.
SATA drives need an IDE TO SATA bridge board. No drivers involved. KINGWIN ADP-06
